POTD is awesome, I've switched to DPS from tanking seeing how the community is (Good luck future tanks...) And here's what I did : I went inside floor 51 solo with a fixed party, took a look at all the skills and checked synergy, then I placed them all on my keybinds to ensure it makes sense. Once I've done that, I left the floor then queued for matched party. I am now level 50 on my dragoon and can say that I'm used to skills, orders and keybinds associated. Personnaly I think it is a good way to train as DPS.
